RESILIENT WHEEL.

Specioation of Letters Patent.

Patented Sept. 4, 1917.

Application led December 6, 1916. Serial No. 135,327.

To all whom t may concern:

Be it known that I, HmAM C. ANDERSON,

a citizen of the United States, and a resident of the city of New York, Westchester, .5 borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Resilient Wheel, of which the following is a full, clear, and exact description.

This invention relates to resilient wheels, and has particular reference to that type of wheels in which there is provided a pneumatic cushion remote from the tread, and hence protected from all of the usual conditions which tend to cause damage or deterioration tothe cushion.

Among the objects of the invention, therefore, is to provide a wheel including a rigid casing, in which is loosely housed a pneumatic tube construction, said casing being provided with openings through which the spokes of the wheel project, any suitable solid rim and tire construction being provided for the tread. i

Another object of the invention is to provide means for excluding dust, dirt or other extraneous matter from said casing and yet provide for sufficient relative movement between the spokes and the casing for the purposes of the device.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, Still for the purpose of illustrating a ractical embodiment thereof reference is ad to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a side elevation of my improved wheel, portions being broken away;

Fig. 2 is a transverse section on the broken line 2-2 of Fig. 1;

Fig. 3 is a detail of the shoe'; and

Fig. 4 is a detail perspective view of one of the dust guard devices above referred to.

Referring now more particularly to the drawings, I show a wheel comprisin a hub 10, secured to or journaled upon a spindle 11 by means of a nut 12. The outer end of the hub is threaded to receive a cap 13 having a ange 14.

The wheel also comprises a hollow rigid casing composed of two principal parts 15 and 16. These casing parts comprise companion flanges 17 and 18 having registering holes through which any suitable fasteners 19 are passed to lock the parts of the casing together. The part 15 has a hub portion 20 extending laterally beyond the central plane of the wheel, and against which the relatively short hub portion21 of the outer casing member 16 is squarely set. The outer surface of the outer casing part or disk 16 is countersunk at 14 to accommodate the flange 14 of the cap 13, which holds the casing upon the main hub 10. The periphery 22 of the casing part 15 is of short cylindrical form and has a slightly shorter radius than the flanges 17 and 18 of the casing. This periphery 22 is provided with a circular series of circumferentially extending slots 23, having their axes or centers lying in the central plane of the wheel.

Within the casing and surrounding the hub portions thereof, is a pneumatic casing or shoe 24 provided with a lacer 25 adjacent to the hub. The inner portion of the shoe is provided with a circumferential slit 26 and a flap 27 overlaps said slit, the lacer making a close fitting connection or closure for the slit. This provides means for introducing a flexible inner tube 28 of any usual or approved nature and provided with a filling tube 29 projecting outwardly from the shoe and through the cylindrical periphery 22 of the casing. The pneumatic shoe 24 is located not only against the hub 20 of the casing, but fairly snugly between the parallel side walls of the casing parts 15 and 16.

A rigid annular inner rim 30 of metal or its equivalent is located within the casing and is fitted around the outer portion of the shoe, but adapted to float with respect to the axis of the spindle 11. The spokes 31 are secured at their inner ends at 32 in bosses formed rigidly upon the outer portion of the inner rim 30. The spokes thence project radially outwardly through the slots 23 in the periphery of the casing and are secured in any usual or approved manner to the felly 33 upon which the outer rim 34 is mounted. A solid tire 35 is carried by the outer rim. The Slots 23 provide for movement of the axle and wheel hub relative to the outer or tread portions of the wheel according to the load or obstructions which may be encountered along the roadway, the resiliency the shoe and inner tube movement.

Each slot 23 is kept substantially closed by means of a cap plate 36 fitted snugly upon the outer surface of the cylindrical portion 22 of the casing and through the hole 36 of which the spoke projects. That is to say, while the spoke may be free to move longitudinally through thefhole 36', the plate 36 will move with the spoke circumferentially of the wheel or longitudinally of the slot 23 covered thereby. Outward or radial displacement of theplates with respect to the casing is prevented by means of guide pins 37 or their equivalent secured to the casing and overlapping the edges of the plates.

I claim:

The combination of a rigid hollow casing having opposed side sections, provided with spaced parallel walls and inwardly projectof permitting such masses ing opposed hub portions, the said walls projecting outwardly from the hub portions at right angles to the axis of said hub portions and forming guides, one of said side sections having an outer integral cylindrical portion provided with a flange to which the outer portion of the other side section is bolted, a hub on which said casing is supported, having a flanged cap removably as-- sociated therewith and 'engaging the outer side section to clamp the sections of the casing adjacent their hub portions upon said hub, a pneumatic tube seated within the inner portion of the casing around the said hub portions, a rigid ring within the casing against the outer portion of the said tube, a movable tread member externally of the casing, and spokes extending within the casing from said tread member and secured to said ring.
